error-handling-patterns

Cross-language error handling standardizes failures using language-specific patterns. This approach enforces explicit error types and context preservation to build resilient applications consistently across Python, TypeScript, Rust, and Go.

Prevent cascading failures by applying resilience primitives like retry strategies, exponential backoff, and circuit breakers. These patterns stop processes from repeatedly hitting broken dependencies, isolating faults and maintaining overall system stability.

Preserve context in error messages by building context-rich errors. Structure your failures with specific codes, descriptive messages, and metadata to simplify debugging and monitoring across your fault-tolerant systems.

Graceful degradation is supported through fallbacks and safe defaults. When dependencies fail, this pattern preserves partial functionality and prevents total application failure during API design and service integration.

Use result types instead of exceptions when working in languages like Rust or Go that favor explicit error handling. Result types model failures as values, enforcing explicit checks and reducing unhandled exceptions in fault-tolerant systems.
